Remarks.—The jumping mice listed above have been compared with specimens of Z. h. hudsonius from Ontario and Michigan. The zone of contact between Z. h. hudsonius and Z. h. alascensis is still unknown; Alcorn obtained no specimens between Irons Creek and Whitehorse. To my knowledge there are no records from this extensive area.
